The Spectral Gravity Sub-Programme

The spectral gravity sub-programme of the Cosmochrony corpus addresses a single central question: why does the effective metric g^ = 2^ satisfy the Einstein equations? Starting from the projective spectral entropy functional S_g = 12' Ag, the sub-programme derives the Einstein tensor as the infrared-dominant response of the renormalized metric variation, reformulates it as a spectral equilibrium condition, extends it causally to gravitational wave propagation, and provides its ultraviolet Born–Infeld completion. The logical chain is: \ S_[g \;\; ₆S_ c₄₇ G_ \;\; G_ = 8G₍ T_^ () \;\; causal completion \;\; BI completion. \] The sub-programme is constituted by four papers: Gravity 3. 0, Thermodynamics, Lorentz/CausalPropagation, and BornInfeld. The scope is the gravitational sector in the absence of matter; full coupled field equations G_ = 8G₍ T_ with matter in Lorentzian signature remain an open deliverable.
